As Will-be observed upon refa smallsprocket gear 39. Chains 40 operate 95 erence to Figure 4 thecompartment`13 is over sprocket wheels 33, `carried by wheels providedwith a grate 14 spaced from the 42 andthe small sprocketgears 39 carriedbottom thereof, opening 15 through which by axle 37. Thus it will beobserved that e access may be had below the grate ,`a-n openwhen thewheels 32 Vare rotated, chains 40 ing 16 just abovethe grate, which maybe will cause rotation of sprocket gears 39 which. 100 closed, whendesired, bythe door 17 and the will in turn rotate shaft 37 and therou'pper end ofthe compartment is divided ott' tation of the shaft 37will be imparted to into a containing space [18 through the theshaft 34through `the .medium ofl co"- mediuin of a partial partit-ion 19. Thepar meshing gears 3G and 38 thus rotating fan Vtition 19' does not'extend entirely across the member f The coinpartment12isprovided 105compartment 13 vbut leaves an opening 2() with openings 41 at the lowerrear ends, through which the contents of the container which openingslead into depending angular 18 can be fed downwardly. The opening 20dispensing spouts 42 Ithat are carried eX- shown in Figure 1.

rl`he operators seat 45 is carried upon a spring member 46 whose forwardend is secured to the bottom member 1() of the niachine, as at 47, sothat the seat will assume a position slightly in the rear of the bodyportion of the. machine and about on the level of the top thereof.

Hinged covers 48 are provided for compartment 13 while removable covers49 close the upper ends of compartment 12.

Frein the foregoing, it will be observed that when there is a fire onthe grate 14 and the poisonous powder from container 18 is fed into thefire a smoke will be generated in compartment 13 which will pass throughopening 29 in compartment 12. As the machine moves forward, the fan 35will be rotated thus forcing the smoke out of compartment 12 throughopening 41 into spout 42 and outwardly through nozzles 44. The

Y nozzles 44 assume a position directly over or between the plants overwhich the machine travels so that the smoke emitted therefrom willcirculate among the plants and destroy the boll weevil or other insectswhich infect the latter.

In order to insure a more thorough distribution of the smoke mixturefrom nozzle 44 about the plants through which the machine travels, andat the same time to cause the smoke to be held about the plants, a shorttime after it is emitted from the nozzle, I provide a cover likearrangement to be positioned over the nozzles 44. IVith this in View, Iprovide a cover like structure which consists of side pieces 50,connected at their rear ends by a simicircular bracket 51 andintermediate thereof by a slightly larger semicircular bracket 52. rIhespace between brackets 51 and 52 is covered by a suitable covering 53while a connecting rod 54 is employed to connect the upper ends of thebracket and form a reinforcementfor the cover. At the rear end thematerial that forms the cover proper is extended beyond bracket 51 toyform a sheet or curtain 55 slit at spaced points, as at 56, topartially close the rear end of the cover, yet to permit the machine topass over the cotton plants.

The front end of members 50 are connected as at 57, through a bracket 58carried by the body portion of the machine. It is preferable that themembers 50 be placed only slightly above the ground over which themachine travels so that the cover 53 will form a hood over the cottonplants and thus insure a better distribution of the smoke to the endthat boll weevil and other insects will be destroyed. f

The sides of the vehicle may be provided with aprons formingcontinuations of the side portions of hood 53, and these aprons dependfrom the outer sides of the members A and B and terminate a shortdistance above the ground. The aprons, as well as the side portions ofhood 53, are attached at their lower ends to the side members 50, thelatter also having attached thereto the lower ends of the stays 51-52.rlhe stay 52 has secured to its upper portion the lower end of a link63, the upper end thereofl being attached to a rearwardly projecting armforming part of a lever 60 pivoted as at 61 to a part of the vehicle andtraveling upon a segment 62. The handle 64 of the lever 60 is inconvenient reach of the driver occupying the seat 45, and suitable latcharrangement associated with the lever and segment maintains the lever indesired positions of adjustment. It is obvious from this constructionthat the hood may be adjusted toward or away from the ground, tocompensate for growing plants of various heights. By extending theaprons forwardly from the sides of the hood, an elongated fume confiningspace is provided, the utility' of which is apparent, as the fumes maybe more intimately brought into contact with the plants in beingliberated beneath the hood.

Suitable brake means and other appurtenant mechanism may be employed inplacing the machine in actual practice, but inasmuch as it does not lormsubject matter of the present invention, it has'not been described orshown in detail.

Upon reference to Figure 1, it will be noted that I provide a tongue orother connecting member 59 that projects forwardly of the body portionof the machine for purposes that are obvious.

The powder to be used in container 18 is of a poisonous nature and isdesigned to generate. a dense smoke with poison fumes when fed on thefire on the grate 14. The powder, while generating poisonous fumes thatwill destroy insects such as boll weevil, the fumes will not be foundharmful to the human system.

From the foregoing. it is believed that the advantages and novelfeatures of my invention will be readily understood and thereforefurther detailed description is deemed unnecessary. Y

What is claimed is:-

In a device of the class described, a vehicle having a platform. albracket depending from the forward end of said vehicle and having itsends outturned and disposed horizontally and relatively close to theground, side bars disposed beneath said vehicle and hingedly connectedat their forward ends to said out turned portions of the bracket, a pairof yoke members arranged in inverted position in spaced relation beyondthe rear 1,630,016 e I d 3 of seid Vehicle and having thenIlOWer ends onSaid vehe1e,a: connection between said Secured to sind Sxde members, arod Acon- `'lever and one ofsald yokes,`and fume pronectng the upperportions of said yoke ducngappara-tus on said Vehicle to direct` 10members together, L hood supported by said fumes into the forward endlof said hood. vIi yoke members and rod, aprons depending In testimonywhereof I afx my signature.
